Azura Quilalea Private Island, Mozambique

The perfect Crusoe fantasy: nine thoroughly romantic seafront villas on a baobab-studded island, with pathways through shady forests to crescent beaches. It's enchanting and relaxing; the kind of place where you never bother to lock your room, and spend your days barefoot in a sarong. Turtles heave up to lay their eggs on the beach, and there's a reef so close you can snorkel back to your room after breakfast.
